will now be more I particularly described reference being. had to the said drawing in I which indicates a casing which may be of any suitablesize and shape and within whicha supporting frame 6 is mounted extending vertically and transversely of the frame. Journaled upon the said frame 6 is a trans-f verseshaft 7. engaging journal boxes 8 se; cured to the said frame. The shaft 7 gcarrie the picture drum of the mechanism, sai drum being made up of a hub portion 9 which runs loosely upon the shaft 7 and is limited against slipping thereon in one dis rectiorf by a collar 10 which is clamped thereon. I

run sections 12 adapted to hold the picture cards of the mechanism. The said picture sections are made of different lengths, each of said sections being preferably made ofa proper size to receive a tunes, or a group particular subject.

The rib sections 12 are provided with hook shaped flanges 13 at one edge adapted to hook upon the rim 11 of the hub and the of pictures relating to} other edge of each section is. held in place with respect to the hub by means of set screws i i which are passed through coinciding apertures in the said sections and the rim of the hub as clearly shown in Fig. 3. Each of said rim sections 12 is formed with a central peripheral tenon 15 extend; ing from one end of the section to the other,

The said peripheral tenons are adapted to engage correspondingly shaped mortises or recesses 16 formed upon picture cards 17 as illustrated in Fig. 5 ofthe drawing. The picture cards are slipped upon the mortises 15 of each section and are spaced withrespect to each other b means of transverse bars or strips 18 applied to one face of each card. The strips 18 are located near the mortises 16 permitting the inner edges of the cards to come together, while the outer edges of said cards are forced by the said strips to'spread to a suitable degree with respect to each other as shown in Fig. I}. in order to hold each group of picture cards The hubhas a rim portion 11 with broad side flanges to which are secured outer given group of pic-' upon each rim section, end plates 19 are secured to the ends of the sections, usually by removable screws.

cry of the rim 11, edge lates or rings 20 are secured to the edges the said rim sections by suitable screws, the said rings operatingto hold the picture cards in lens 21. electric lam 's, are mounted in the casing so as to re ect light upon the pictures in projecting them through the'lens, 21. As

the picture drum is rotated to bring the pictures successively before the lens in the usual manner in such devices, they are held by a retarding plate 23 which is adjustably connected with a hinge plate -24. The saidhinge plate has a hinged connection with the upper transverse portion of theframe 6 and is provided with an elongated slot indicated in dotted lines in Fig. 2 in which a screw bolt 25 is adapted to be set fo'rholding the retarding plate 23 in desu'ed posltion with respect to said hinge plate. The

outer end of the plate 23' is provided with a standard 26 having a socket or recess formed therein to receive the end of a rod 27. The said rod 27 is screw threaded for a portion of its length and adapted to ext'end into a threaded bore formed in a hinged V b 28. A lock nut 29 also upon the threaded portion of said rod 27 is employed for "holding the parts in adjusted relation to each other. The adjustment of the plate 23 .and the rod 27 issuch as to causethe said plate to bear upon the edges of the pictures as the picture wheel is turned, allowing them to'fall in succession opposite the lens 21.

The parts can of course be adjusted toexert a greater or a less pressure for detaining the pictures as found needful to secure a Therotation of the picture drum constitutes an important feature of the invention and particu arly the means OftranSmitting movement to the hub of the picture drum. Themode oftransmission is such that the pictures can be run. successively for a given period andthe'n held stationary for ex osiven picture for ashor't' perio of Such operation is desirable under given circumstances as for instance when advertis ing cards are laced upon a drum and it is desired to hol them a predetermined period beforethe lens. In accomplishing the rotation of the drum, the shaft 7 is turned by any suitable mechanism, but usuall by means of a sprocketwheel 30 which is'secured upon the said shaft 7 and is connected by means of a sprocket chain 31 with a sprocket wheel 32 secured to a counter shaft 33. The said counter shaft .is mounted u on hearings in the framing of the mechanism and carries'a worm gear 34 which meshes The cards when thus. mounted upon the rim sections of the drum are ready to be brought in position oppositean opening in the casing'5 provided with a. One .or more lights 22, usually g with a worm 35 secured to a shaft-36 which extends at right angles to the said counter shaft 33. v The shaft 36 also carries a worm gear 37 which-engages and meshes with a worm 38 secured to a shaft 39 mounted at; a right angles to the shaft 36.. The said shaft 39 carries a friction disk 40 of suitablerdiameter and arran edto engage'a friction pinion 41 which Is splined upon a' motor shaft 42. The said motor shaft is connected with the armature off'an v suitable motor as 43, an electric motor being generally'employed. By means of the mechanism thus described, the movement communicated to .the shaft 7 is through frictional so that-,the partscannot be broken off if they should become caught or prevented from operating in their usual manner. The position of the friction pinions 41 opposite the face of the friction disk 40 also controls the speed i of the movement imparted to the shaft 7-. I

secured to the hub 9 of the picture drum, and usually by means ofv screws 45. which engage screw threaded sockets 52 formed in lateral projections upon the said hub9 as clearly shown in Figs. 3 and 4. The outer face of the clutch member 4 which ispreferably in disk form, is provided with a seri'es of teeth 46 arranged near the periphery .of the disk. .These teeth are .adaptedto be engaged by teeth-47 formed upon the other member 48 of the clutch. The said member 48 is arranged to'so engage the shaft 7 as to 3 turn therewith and for this purpose is pro.- vided with rollers 49 journaled at their ends in the hub of theclutch member 48 so as lie parallel with each other and upon op 9';

site sides of the shaft 7. The said shaft isformed with oppositely, arranged flat sur- 1 faces '50 so as to engage the said rollers 43; The flattened ortion of the shaft is madegof- I I sufliciient lengt to. permit the clutch member 48.to"be moved into and out of en gement with the clutch member 44', and ,saidrollersz 49- through their;,'engaigement with the said flattened urface. 50- cause the clutch mem er vfi r Wit jt shaft. A sp .51. mounted-upon the shaft 7 "and interpbsed between the clutch members normally to separate them". Theclutchmember 48j-is adapted to be intermittently forced 'into e'ngagement with the teeth of the "clutch member 44 and forthis purpose is provided with outwardly projecting standards usually in the form'of 'brackets within Which rollers .56 are journaled. The rollers are made of su abl id t ee e m w iske formedup'oh the perip eraledges of cams 57 of the cam plate. Upon engaging said earns, the clutch members will greases plate 58 which surrounds the shaft "l but is fastened'to a vertical standard 59 mounted Within the casing 5.. The cam plate 58 is thus held stationary at all times, but as the shaft '2' rotates carrying the clutch member .8 with it, the rollers 5il-vvill ride inwardly upon the cams 5? so that the tee h of the clutch memher 8 are forced engagement with the teeth, of the clutch member 44, and the picture drum will be temporarily i'otated. As soon as the rollers 56 run ofi from the cams 5?, the clutch member will be separated again by the spring 51. The friction of the pictures upon the retardin plate 23 will then temporarily hold the sai picture drum from turning. It will be understood that by regulatin. the cam projections of the cam late wit respect. to the picture drum an also with r spect to the rollers carried by the clutch member 48, the periods when the picture drum will be held stationary may be regulated.

The operation of the parts for securing an intermittent holding ofthe picture drum in stationary position will be automatically accomplished.

The operation of the device will be evident from the above description. The motor43 is set in operation, the friction pinions 41 being so arranged with respect to the disk 40 as to secure a desired speed in the movement of the parts. The intermediate gear ing will cause the rotation of the shaft 'i, but the picture drum will not be actuated since it loosely engages said shaft 7 until the rollers 56 of the clutch member 48 engage the the rollers be brought to ether and the picture drum will be rotated controlled by the length of the cam surface. After the rollers drop from the cam surface and the clutch members are separated, the picture drum will stand static a short period.
